Device for curing pipeline inner resin linings

Abstract

A device for curing inner pipeline linings made with the use of a resin compound cured by electromagnetic radiation, the device being equipped with a central polyhedral body provided with LEDs generating the radiation by emitting waves with lengths from the range 200-500 nm, to cause curing of the resin compound. The LEDs are shielded with an element made of a transparent plastic or quartz glass with a body made of monolithic cylindrical solids having along the whole of length of their outside surfaces with radii identical flat facets-chords symmetrically distributed on the surfaces, to which detachably attached are plastic plates equipped with LEDs emitting electromagnetic radiation with definite range of wavelengths.

Description

FIELD OF THE INVENTION[0001]The subject of the invention is a device for curing inner linings in pipelines introduced into them in the form of lining tubes impregnated with a resin.BACKGROUND OF THE INVENTION[0002]Worn-out and leaking pipelines, including sanitary sewerage systems, deteriorated usually because of insufficient maintenance, are subject to renovation by means of lining tubes impregnated with resins, dragged into the pipeline and bonding them with inner surface of the pipeline in order to eliminate leakage and soaking of carried liquids through the pipeline walls showing destructive impact on natural environment.[0003]From Polish patent description No. PL202527 known is a method and a set for renovation of pipelines, where the renovation method according to that invention is characterised in that a liming is placed inside the pipeline and then pressed against the inner surface of the pipeline by means of rings, while ends of the lining are sealed with the use of any kno...

AI Technical Summary

Benefits of technology

The invention relates to a device for curing the resin lining of pipelines. The device has a unique cooling system that circulates air over the surface of the LEDs and the radiators simultaneously. This leads to more uniform temperature control and better protection against damage or fire. The LEDs are mounted on separate radiators connected to the device's body, which ensures consistent operating and cooling conditions. The device also has a scheduling feature that allows for alternating LED activation and deactivation to achieve the required radiation dose while minimizing power consumption and preventing overheating. This creates a "spinning" effect that can deliver the required amount of radiation onto the target surface. Overall, this device improves the efficiency and safety of pipeline repair processes.

Problems solved by technology

However, it turned out that despite a number of good points characterising this method of curing resin pipeline linings, including minimisation of energy consumption compared with conventional method of curing resin linings by means of hot water of steam, the device has a serious flaw consisting in that UV radiation emitted from the device is very harmful to health and threatens lives of workers operating the devices.
